Since 39b2bbe3d715 (gpio: add flags argument to gpiod_get*() functions)
which appeared in v3.17-rc1, the gpiod_get* functions take an additional
parameter that allows to specify direction and initial value for output.
Simplify driver accordingly which even make error checking more correct
because gpiod_direction_{in,out}put might fail. Furthermore this is one
caller less that stops us making the flags argument to gpiod_get*()
mandatory.

Hello,
I intend to make the flags parameter to gpiod_get* mandatory once
4.2-rc1 arrives. So unless this patch makes it in, I'd like to get an
Ack to take it via the gpio tree together with the change to gpiod_get.
Note this patch depends on
551e306905ef (NFC: nxp-nci_i2c: Add support for enumerating through ACPI)
which only appeared in today's next.
Best regards
Uwe
